Good purchase
Size: 4 Panel-88‘’Wide, Color: Black
Very easy to assemble. Good quality. The material is thick enough to block the light and gives much needed privacy.

Storage may be a problem

Worked as expected however storing it was not so easy. The feet did not collapse one over the other but provide privacy.

Perfect size, good privacy
Size: 4 Panel-88‘’Wide, Color: Black
This is a good divider. The dark, thick panels provide blockage from the light. Assembly was not very hard, but it wasn't simple. I ordered this product two times in the past couple of weeks. The first time I assembled it, I noticed that the picture assembly directions aren't completely accurate. The labeled parts don't match the labels on the instructions. The wrench included in my box is too big for any of the bolts or screws used for assembly. After getting the right tools and matching against the instructions, I finally got it assembled. The divider I ordered this week is missing two wheels and there is no number for calling the supplier; thus, I seem forced to return it, instead of easily getting the two wheels. Once assembled, I am pleased with the end product and I consider it a good value.
